n is number of sides of polygon

#b

put n=60

  • 60sin(360/2(60))
  • 60sin(360/120)
  • 60sin(3)
  • 3.14016

π=3.14159

Difference

  • 3.14159-3.14016
  • 0.00143

Answer:

Given expression:


n * \sin\left((360)/(2n)\right)

a) The
n stands for the number of sides of a regular polygon.

b) If
n=60


\implies 60 * \sin\left((360)/(2(60))\right)=60 \sin(3)=3.140157375...

Therefore, the difference between the perimeter and π is:


\implies \pi - 60 \sin(3)=0.001435279013...
